Engineering, by Frederick W. Pomeroy, one of his four colossal (around twice life-size) bronze statues on the upstream side of Vauxhall Bridge, a Grade II* listed bridge across the Thames from Vauxhall to Pimlico, in south London. Installed here in 1907, and beautifully draped like the others, this female figure holds a mallet or hammer in one hand. It rests on an anvil by her feet. In the other hand, she holds a model of a steam engine with a cylinder and flywheel — just the kind that once powered industries of all kinds, from cotton mills and factories to pumping stations and so forth. Like Architecture, the figure as a whole can only be seen clearly, from the front, by river.

Writing about the London bridges in 1921, the architect Sir Reginald Blomfield said how important it was for a bridge to be "a symbol of the life and civilization of the people who use that bridge" (101). The model held by this figure shows an important aspect of London, without which it could never have become the powerhouse of empire.
